Hello Everybody, New to the OAKLEYFORUM.com. I've got a pair of 2007 Oakleys. Ducati Juliet X metal with a carbon frame and black Iridium lenses. Everything I have researched tells me they are authentic. Coin, box, frame and lenses ect. I had a guy tell me they were fake becouse there is NOT a serial number or an identification type of number on the inside of the frame. I purchased them new back in 07 for $350.00. can someone give me some information on how to tell if they are authentic or fake?
